Quad 2-input NAND Schmitt trigger

Product specification

74AHC132; 74AHCT132

FEATURES

• ESD protection:

HBM EIA/JESD22-A114-A

exceeds 2000 V;

MM EIA/JESD22-A115-A

exceeds 200 V

CDM EIA/JESD22-C101

exceeds 1000 V

• Balanced propagation delays

• Inputs accepts voltages higher than

VCC

• For AHC only:

operates with CMOS input levels

• For AHCT only:

operates with TTL input levels

• Specified from

−40 to +85 and +125 °C.

DESCRIPTION

The 74AHC/AHCT132 are

high-speed Si-gate CMOS devices

and are pin compatible with Low

power Schottky TTL (LSTTL). They

are specified in compliance with

JEDEC standard No. 7A.

The 74AHC/AHCT132 contain four

2-input NAND gates which accept

standard input signals. They are

capable of transforming slowly

changing input signals into sharply

defined, jitter free output signals.

The gate switches at different points

for positive and negative-going

signals. The difference between the

positive voltage VT+ and the negative

VT− is defined as the hysteresis

voltage VH.

Notes

1. CPD is used to determine the dynamic power dissipation (PD in µW).

PD = CPD × VCC2 × fi + ∑ (CL × VCC2 × fo) where:

fi = input frequency in MHz;

fo = output frequency in MHz;

∑ (CL × VCC2 × fo) = sum of outputs;

CL = output load capacitance in pF;

VCC = supply voltage in Volts.

2. The condition is VI = GND to VCC.
